“ I shall always attribute my uncertain start in New Zealand to the fact that I was introduced too early to what is knows as the 'five o'clock swill'. The phrase has, when you consider it, a wonderful pastoral - one might almost say idyllic - ring to it. It conjures up a picture of fat but hungry porcines, all freshly scrubbed, eagerly and gratefully partaking of their warm mash from the horny but kindly hands of the jovial farmer, a twinkling eyed son of the soil.Nothing could be further from the truth.The five o'clock swill is the direct result of New Zealand's imbecilic licensing laws. In order to prevent people getting drunk the pubs close at six, just after the workers leave work. This means they have to leave their place of employment, rush frantically to the nearest pub, and make a desperate attempt to drink as much beer as they can in the shortest possible time. As a means of cutting down drunkenness, this is quite one of the most illogical deterrents I have come across. ”
